http://aml.engineering.columbia.edu/ntm/level1/ch02/html/l1c02s03.html WebLight continua extending from the i.r. to the u.v. are generated with picosecond laser pulses in liquids and solids. It is demonstrated that the light spectra in water are produced by stimulated parametric fourphoton interactions, which are resonantly enhanced by single and difference frequency resonances of the non-linear susceptibility X (3).

WebLaser light can be emitted in a tight beam that does not grow in size at a distance from the laser. This means that the same degree of hazard can be present both close to and far … Weboperation of semiconductor lasers. 11.4.2 Laser Output Power: We also need expressions for the light coming out of the laser. Photons leave the cavity in two ways; they can either escape from the end facets (or mirrors) or they can get absorbed by the cavity. Only the photons that leave the cavity from the mirrors constitute useful output. dagenham priory school photos
